Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The following example demonstrates post-mortem debugging using the pdb command."

A block of code is set as follows:

version: "2.0"
language: en
pipeline:
  - name: WhitespaceTokenizer
  - name: LanguageModelFeaturizer

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

WebChat.default.init({          selector: "#webchat",          initPayload: "Hello",

Any command-line input or output is written as follows:

python -m pdb -c continue <XXX>/rasa/__main__.py train

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "Click on the Cancel button."
